IMPROVED FASTENINGS FOR LAMP-CHIMNEYS.

Specification forming part of Letters Patent No. 37,119, dated December 9, 1862.

To all whom it may concern.-

Be it known that I, LUTHER 0. WHITE, of Waterbury, in New Haven county, in the State of Connecticut, have invented a new and Improved Mode of Fastening Lamp Chimneys and Shades on Burners; and I do hereby declare that the following is a full, clear, and eztact description thereof, reference being bad to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification, in which Figure 1 is an interior sectional view of a coal-oil burner with my invent-ion applied to it and pressed backward in order to show the action of the wire lever. Fig. 2 is also an interior sectional view of a coal-oil burner with my invention applied to it and pressed forward in order to show the action of the wire lever. Fig. 3 is an exterior view of a coal-oil burner with my invention applied to it in connection with a ohimney.' Fig. 4c is a detached view of a part of my invention, showing its shape, it being somewhat like a hawks bill. Fig. 5 is an external view of a section of a coal-oil burner,showin g the bolt on which the hawks bill works and the way in which it is attached to the burner.

Similar letters of reference indicate corresponding parts in the several figures.

This invention relates to an improvement in fastenings for lamp chimneys and shades.

The object of the invention is to adapt a self-aotin g fastening, which will hold the chimney firmly to its place. This objectis attained by using a piece of metal of peculiar shape, it having three projections or teeth to it, which is fastened to the burner by means of a bolt placed a little ways below the ornamental rim or gallery. A piece of brass wire, curved with the burner, is placed in the interior of the same, one end of which works in the lower projection, and the other end in one of. the small perforations in the burner, so that the wire acts as a lever-prop when the projections are brought either backward or forward in order to adjust the chimney.

To enable those skilled in the art to fully understand and construct my invention, 1 will proceed to describe it.

A represents an ordinary coal-oil burner, in the side of which a piece of metal, shaped somewhat like a hawks'bill, as shown at B in Figs. 1 and 4, is fastened by means of a bolt, as shown at c in Figs. 1 and 3. There are places formed in the burner for the ends of this boltto rest in, no solder being used, as shown at d in Fig. 5. To the hawks bill B are three projections, as seen at e, f, and g in Figs. 1, 2, and 4, places being out out in the burner for their entrance. In the lower projection a hole is made, in which the end of a piece of brass wire enters, as shown at hin Figs. 1 and 2, which is bent round with the burner, as shown at J in Figs.1 and 2, the other end entering one of the small perforations in the burner, as shown at k in Figs. 1 and 2. XVhen the hawks bill B is brought backward, as shown in Fig. 1, or forward, as shown in Fig. 2, this wireacts as a lever, keeping the hawks bill in either position by means of one end turning in perforation h and the other end turning in perforation 7.". When desirable to adjust the chimney, the flange is placed under teeth m in Figs. 1 and 2, and then pressed down upon projection a, when it suddenly causes the hawks bill to move backward and then forward again as quickly, thus holding the chimney firmly to its place by means of the wire lever J. The chimney can likewise be as readily adjusted when the hawks bill B is already backward, as in Fig. 1, by placing the flange in a similar manner as before under teeth m, and pressing it down upon projection f, when the hawks 'billB will quickly move forward against the chimney and hold it tightly to its place. When requisite to remove the chimney, the thumb is pressed upon point a of hawks bill'B, as shown in Fig. 3, when it is quickly broughtbackward, as shown in Fig.1, so that the chimney can easily be lifted out. 7

What I claim as my inventien, and desire to secure by Letters Patent, is-- 'l. The peculiar construction of hawks bill B, or'its equivalent, as shown in Figs. 1, 2, 3, and 4, and the mode-of throwing it either backward or forward, and holding it in either position by means of the wire lever J, or its equivalent, the ends of said lever being loose in perforations h and k.

2.,The middle projection or tooth, f, or its equivalent, as shown in Figs. 1, 2, and 4,which throws the hawks bill forward by gently pressingthe base of the chimney upon it independentiy of the np per projeetibme, which bolt-supports 07, formed in the shell of the secures the chimney to the burner. burner, as shown in Fig.5., the. whole being 3.
